THIS lively game will give you all the thrills of knocking the daylights out of an enemy city with well-placed “demolition bombs” without the least danger to the bombardier, although the area below is bristling with antiaircraft guns.

The bomber (Figs. 3 and 4) slides on a revolving arm supported by a central post (Fig. 2) and is moved by hand until it is over target selected. By looking through the bombsight with its cross-wires the airman can get a direct line on target and release marble “bomb” by a hand lever.

Civilians can join in one of the soldier’s favorite pastimes—identifying combat aircraft—with playing cards that have silhouettes of Allied and enemy planes on their faces. The United States planes are spades, British are hearts, German are diamonds, and Japanese are clubs. In the corners are the “pip” signs. The airplane card idea was suggested by officers of the Third Air Corps, Tampa, Fla., who have been conducting classes in aircraft identification.

How to Make Money from These Plans OF four items illustrated here, only the “Human Roulette Wheel” requires much work. Three are well fitted for profitable sales, the roulette wheel and the illusion box most so. The track circuit for toy trains is an ideal window display. Sell your services to local toy stores, offering to arrange for them an automatic display which is mysterious and attracts attention.

Aviation fans may play at a round-the-world race in a new game designed by Assen Jordanoff, veteran pilot and frequent contributor to Popular Science Monthly. Each of the players, which may number up to twenty, chooses a toy plane that moves across a large-scale map of the world.

SURE THEY WORK—and you don’t even need batteries! What are they? Just a pair of sound-powered telephones that are certain to turn a couple of kids into a pair of happy hooligans for many a fun-time session. And what’s the secret? There really isn’t any— other than the fact that a crystal earphone will work as either an earphone or a microphone, depending on whether you talk or listen.

RAILROADS, banks, and other big business organizations have no monopoly on the merger idea. Inventors, bereft of original ideas, are now turning their attention to combining separate ideas into one complete whole merging, as it were, the well-known ideas of the past.

Nowhere, perhaps, has this tendency been so pronounced as in the world of minor sports. Polo long ago merged with swimming in a game known as water polo, tennis and fly-swatting emerged as ping-pong, dominoes and rummy met in China and returned as mah jong, while labyrinth puzzles and golf united in the popular craze of putt-putt.

Give a boy a tree house and he can have all the adventures of a safari in his own backyard.

For adventurous little boys, a tree house offers many delights. It is a hideaway, a place to store secret treasures, a camping-out spot. From it one can see without being seen. It can be reached by ladder only and it is relatively inaccessible to adults.

THE bathtub battle fleet has a colorful new recruit—a plastic “rocket” submarine that performs a series of gliding dives on- pill-power. The manufacturer, Payne Products, Inc., of Midland, Mich., supplies effervescent tablets designed to propel the craft for six or seven minutes. Agitating the water slightly makes the submarine dive oftener.

When the submarine is placed under water to start its voyage, the gas-releasing “fuel” acts as a pump, expelling water and sending the craft to the surface. Then it submerges again, and the cycle is repeated. Balance and glide as the toy rises and sinks provide its forward motion.

Archery and Poker Game in One
POKER and archery are combined in a new game that has a target on which are painted all the cards of the poker deck, as shown in the photo above.

The young lady in the photo above, Miss Helen Thompson, wintering at Ormond Beach, Florida, has just shot three aces and a pair of kings—a winning hand.
